TECHNICAL FIELD

[0001] The utility model relates to the technical field of lamps and lanterns illumination, more particularly to a refrigerator lighting lamp. BACKGROUND

[0002] With the rapid development of the retail industry, the requirements of commercial superstores for display effects are higher and higher. In the field of cold chain logistics and food preservation, refrigerators are key equipment for storing and displaying frozen food, beverages, ice cream and other commodities. However, in the existing lighting applications of commercial superstore refrigerators, the light-emitting angle and light pattern of the lamp tube cannot be controlled, resulting in too low effective area illuminance, which cannot highlight the lighting effect. In addition, many additional components need to be assembled in the existing lamp tube body, the processing is complex, the sealing performance is poor, the manufacturing cost is high, and the light rays are not uniformly refracted or reflected at the connection part of the existing lamp tube, resulting in uneven distribution of light rays in the lamp tube irradiation area, thereby forming irregular yellow lines or shadows in the refrigerator. This problem not only affects the lighting effect, but also may affect the display effect of the goods.

[0003] Therefore, the present application proposes a refrigerator irradiation lamp tube by reasonably designing the lamp tube structure and the light source position to solve the problems existing in the prior art. SUMMARY

[0004] The utility model aims at overcoming at least one defect (deficiency) of the prior art, providing a refrigerator lighting lamp, which uses the structure of the lamp tube to increase the optical position to adjust the optical path, so that multiple light paths are superimposed to control the light-emitting angle and light pattern to achieve the predetermined optical effect.

[0005] The technical scheme adopted by the utility model is a refrigerator lighting lamp, which comprises a light-transmitting cover, a base and a light-emitting assembly. The light-transmitting cover is connected with the base. The light-emitting assembly is arranged in the internal space formed by the connection of the light-transmitting cover and the base and is installed on the base. The outer surface of the light-transmitting cover is a light-transmitting surface. The upper part of the inner surface is provided with a concave structure. The lower part of the inner surface is provided with a reflecting structure. The light-emitting surface of the light-emitting assembly covers the concave structure and the reflecting structure.

[0006] According to the different directions of light irradiation, the utility model also provides another structure of a refrigerator lighting lamp. The lamp tube comprises a light-transmitting cover, a base and a pair of light-emitting assemblies. The light-transmitting cover is connected with the base. The pair of light-emitting assemblies are arranged in the internal space formed by the connection of the light-transmitting cover and the base. One end of the pair of light-emitting assemblies is supported on the middle part of the light-transmitting cover, and the other end is supported on the base. The outer surface of the light-transmitting cover is a light-transmitting surface. The upper parts of the two sides of the inner surface are provided with concave structures. The lower parts of the two sides of the inner surface are provided with reflecting structures. The light-emitting surfaces of the pair of light-emitting assemblies are arranged oppositely. The light-emitting surfaces cover the concave structures and the reflecting structures.

[0007] Therefore, in the present application, by reasonably setting the lamp tube structure, when the lamp tube is used, not only the light emitted by the light emitting assembly can be light distribution by the inner recess structure, but also the light emitted by the light emitting assembly can be light distribution by additionally setting a reflection structure in the light transmission cover, thereby increasing the reflection and refraction times of the light by the lamp tube from multiple angles, superimposing multiple light paths, enhancing the brightness and uniformity of the irradiated object, thereby controlling the light emitting angle and light type to achieve the predetermined optical effect.

[0008] Preferably, the opening side of the inner recess structure is close to the light emitting assembly, the side of the inner recess structure away from the light emitting assembly is an arc surface, and the opening size is smaller than the arc surface size, so that the cross section of the inner recess structure is a sector structure.

[0010] Preferably, the reflection structure is a protrusion from the inner surface of the light transmission cover towards the light emitting assembly, and the size gradually decreases along the direction close to the light emitting assembly.

[0011] Preferably, one side of the reflection structure close to the inner recess structure is an arc-shaped curved surface, and the side away from the inner recess structure is a flat surface.

[0012] Preferably, the flat surface is connected with the light transmission surface, and the flat surface is inclined upward to form a certain angle.

[0013] Preferably, the lamp tube further comprises an aluminum extrusion structure connected with the base, which is made by an integrated molding process.

[0014] Aluminum material has good heat conduction performance, which can effectively help the lamp tube dissipate heat and keep the temperature of the lamp tube stable. It is light and corrosion-resistant, suitable for long-term use, especially in environments with high or large humidity. In addition, it has strong plasticity and can be made into various complex shapes according to design requirements. At the same time, the aluminum extrusion integrated molding process makes the components of the lamp tube seamlessly connected, enhances its sealing performance, effectively prevents water vapor and dust from entering, and prolongs the service life.

[0015] Preferably, the outer side of the aluminum extrusion structure is provided with a light blocking strip, and the light blocking strip is at a certain angle with the light transmission surface.

[0016] By setting the light blocking strip, the light can be emitted at different angles, so that the irradiation surface angle can be wider and the brightness of the irradiated object can be enhanced.

[0017] Preferably, the light transmission cover is PC transparent mist or PC transparent stripe, which can effectively optimize the diffusion effect of light and provide uniform illumination.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By distributing the light beam multiple times to increase the number of reflections and refractions, multiple light paths are superimposed, effectively enhancing the brightness and uniformity of the illuminated object and improving the lighting effect.

[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0030] Example 1

[0031] like Figure 1As shown, this embodiment provides a refrigerator lighting tube, which includes: a light-transmitting cover 1, a base 2, and a light-emitting component 3. The light-transmitting cover 1 is connected to the base 2. The light-emitting component 3 is disposed in the internal space formed by the connection between the light-transmitting cover 1 and the base 2 and is mounted on the base 2. Specifically, the base has slots on the top and bottom, and the light-emitting component 3 is disposed in the slots. The outer surface of the light-transmitting cover 1 is a light-transmitting surface, and the inner surface has a concave structure 4 above it and a reflective structure 5 below it. The light-emitting surface of the light-emitting component 3 covers the concave structure 4 and the reflective structure 5.

[0032] like Figure 2 As shown, depending on the direction of light illumination, this application also provides a refrigerator lighting tube with another structure. The tube includes a light-transmitting cover 1, a base 2, and a pair of light-emitting components 3. The light-transmitting cover 1 is connected to the base 2. The pair of light-emitting components 3 are disposed in the internal space formed by the connection between the light-transmitting cover 1 and the base 2, with one end supported on the middle of the light-transmitting cover 1 and the other end supported on the base 2. Specifically, the top of the inner surface of the light-transmitting cover 1 and the bottom of the base 2 are provided with slots, and the two ends of the light-emitting components 3 are respectively fixed in the slots. The outer surface of the light-transmitting cover 1 is a light-transmitting surface, and the upper sides of both sides of the inner surface are provided with concave structures 4, and the lower sides of both sides of the inner surface are provided with reflective structures 5. The light-emitting surfaces of the pair of light-emitting components 3 are arranged opposite to each other, and the light-emitting surfaces cover the concave structures 4 and the reflective structures 5.

[0033] Therefore, in this embodiment, by reasonably setting the lamp tube structure, when the lamp tube is in use, not only can its concave structure 4 be used to distribute the light emitted by the light-emitting component 3, but a reflection structure 5 can also be set in the light-transmitting cover 1 to distribute the light emitted by the light-emitting component 3. This increases the number of reflections and refractions of light by the lamp tube at multiple angles, allowing multiple light paths to be superimposed, enhancing the brightness and uniformity of the illuminated object, thereby controlling the light emission angle and light pattern to achieve the predetermined optical effect.

[0034] Preferably, such as Figures 1-2 As shown, the opening side of the concave structure 4 is close to the light-emitting component 3, and the side of the concave structure 4 away from the light-emitting component 3 is an arc surface. The size of the opening is smaller than the size of the arc surface, so that the cross-section of the concave structure 4 is a fan-shaped structure.

[0035] Preferably, such as Figures 1-4 As shown, the light-transmitting surface is an arc-shaped light-transmitting surface, and the curvature of the arc-shaped light-transmitting surface is greater than that of the arc surface.

[0036] Preferably, such as Figures 1-4As shown, the reflective structure 5 is a protrusion from the inner surface of the light-transmitting cover 1 towards the light-emitting component 3, and its size gradually decreases along the direction close to the light-emitting component 3.

[0037] Preferably, one side of the reflective structure 5 close to the concave structure 4 is an arc-shaped curved surface, and the other side away from the concave structure 4 is a flat surface.

[0038] Preferably, the flat surface is connected with the light-transmitting surface, and the flat surface is inclined upwards to form a certain angle, as shown in Figures 1-2 As shown, the angle formed by the flat surface inclined upwards and the horizontal plane is in the range of 2° to 45°.

[0039] Preferably, as shown in Figure 3 and Figure 4 As shown, the lamp tube further comprises an aluminum extrusion structure 6 connected with the base 2, which is made by an integrated molding process.

[0040] Aluminum has good heat conduction performance, which can effectively help the lamp tube dissipate heat and keep the temperature of the lamp tube stable. In addition, aluminum is light and corrosion-resistant, suitable for long-term use, especially in environments with high or large humidity. Moreover, aluminum has strong plasticity and can be made into various complex shapes according to design requirements. At the same time, the aluminum extrusion integrated molding process makes the components of the lamp tube seamlessly connected, enhances the sealing performance, effectively prevents water vapor and dust from entering, and prolongs the service life.

[0041] Preferably, the outer side of the aluminum extrusion structure 6 is provided with a light-blocking strip 7, and the light-blocking strip 7 forms a certain angle with the light-transmitting surface. As shown in Figures 3-4 As shown, the angle formed by the light-blocking strip 7 and the horizontal plane is in the range of 2° to 45°.

[0042] By setting the light-blocking strip, the light can be emitted at different angles, so that the angle of the irradiation surface can be wider, and the brightness of the irradiated object can be enhanced.

[0043] As shown in Figure 5 The light generated by the light-emitting component 3 enters the inside of the light-transmitting cover 1 through the fan-shaped arc surface of the concave structure 4, and finally is transmitted to the outside through the arc-shaped light-transmitting surface of the light-transmitting cover 1, thereby realizing primary light distribution. The light generated by the light-emitting component 3 passes through the arc-shaped curved surface of the reflective structure 5, then reaches the flat surface of the reflective structure 5 through the inside of the reflective structure 5, and finally the light is reflected through the flat surface and transmitted to the outside through the light-transmitting surface of the light-transmitting cover 1, thereby realizing secondary light distribution.

[0044] Through the above structure, the number of light reflection and refraction of the lamp tube is increased, multiple light distribution is realized, multiple light paths are superimposed, the brightness and uniformity of the irradiated object are enhanced, and the light emitting angle and light type reach the predetermined optical effect.

[0045] As shown in Figure 6 When the light is transmitted to the outside, the light blocking strip 7 arranged on the aluminum extrusion structure 6 can be used to change the irradiation direction of the light, and by setting the angle between the light blocking strip 7 and the light transmission surface, the light can be emitted at different angles, thereby meeting the lighting needs of different customers.

[0046] Preferably, the light transmission cover 1 is PC transparent mist or PC transparent stripe, which can effectively optimize the diffusion effect of the light and provide uniform illumination. Among them, the PC transparent mist lens has a small surface texture structure, which can effectively reduce the direct light of the light source and produce soft scattered light; and the PC transparent stripe lens can uniformly disperse the light through precise stripe design, avoiding strong light spots or shadows, so that the light transmission cover can be selected as PC transparent mist or PC transparent stripe according to customer needs, which helps to improve customer satisfaction.

[0047] Preferably, the lamp tube also adopts a low-temperature adaptability design, which can work stably in a low-temperature environment, adapt to the temperature difference change inside and outside the freezer, ensure the light efficiency and performance stability of the lamp tube, and effectively resist shrinkage, deformation or cracking in a low-temperature environment, thereby prolonging the service life of the lamp tube.

[0048] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the technical scheme of the utility model, and are not a limitation on the specific embodiments of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principles of the utility model claim should be included in the protection scope of the utility model claim.
